Hello,
In order to fulfill CCPA related requests, our customers typically leverage our Privacy API to retrieve, delete, and update customer data based on declared IDs: https://experienceleague.adobe.com/docs/experience-platform/privacy/home.html?lang=en
Some implementation effort on your behalf may be required in order to create a data/privacy management experience for your customers which leverages this API.
Best,
Curtis Oliver | Technical Support Engineer
